Even though La'el Collins is not considered a suspect in the shooting death of a pregnant woman last week, police want to speak to him.

Brittany Mills, 29, is believed by police to be a former girlfriend of Collins.

Collins' attorney, Jim Boren, told police his client is in Chicago getting ready for the NFL draft. But Boren told ESPN he has been in constant contact with the lead detective on the case and he spoke with the district attorney Tuesday.

"We took the investigation seriously," Boren said from his offices Tuesday. "We've tried to rule him out as a suspect. We're going to provide that information to the police, and ultimately [Collins] will sit down and talk to them. But the timing is poor."

Mills was found shot to death, but she was rushed to the hospital where he infant was delivered.

Collins is projected to be a first round pick.

Sources told ESPN a handful of teams have become aware of the incident and would like to know if police determine that Collins is the father of the infant who was delivered after Mills' death. The baby still is receiving medical treatment.
